The adjustable ternally threaded end portion 25 which receives measuring ports 30 are sequentially passed under a llister head screw 26. A rotary measuring discharge aperture II, and as each port comes to cylinder 2'I having a thickness substantially equal rest in that position the measuring port will fill to the length of bearing I9 is provided with a with material from the container II. In this po- 55 sition indexing fingers 46 of member 43 will engage the grooves 35 of cylinder 21, and one of the previously lled measuring ports 30 will come to rest over discharge port 38 of the plate 36, discharging the material in port 30 through port 38 to whatever convenient receptacle the material is desired to be discharged into. The compression of spring arms 4l of spring member 39 will maintain plate 36 closely against face 34 of cylinder 21, and spring member 43 will likewise maintain member 21 against the outer face of base portion I of cap I3. In this manner there will be no danger of leakage of material between the said associated parts, and lling and discharge of ports 30 will be accomplished with no loss of efficiency. If it is desired to change the quantity of material sought to be discharged at each clispensing interval, the adjusting screws 32 may be, by turning, advanced into or retracted from the apertures in measuring ports 30 and the volume content thereoi` decreased or increased as desired.

While I have illustrated and` described the preferred form of construction for carrying my invention into effect, this is capable of variation and modication Without departing from the spirit of the invention. I, therefore, do not Wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. The combination with a container of a dispenser unit comprising a closure cap member having a dispensing aperture, a bearing member lxed on said cap member, a peripherally operable rotatable measuring cylinder mounted on said bearing having a plurality of arcuately spaced measuring apertures, a discharge aperture plate having a discharge aperture, and radially adjustable means to vary the size of said measuring apertures, said means including screws extending into said apertures from the periphery of said cylinder.

2. The combination with a container of a dispenser unit comprising a closure cap member having a dispensing aperture, a bearing member xed on said cap member, a peripherally operable rotatable measuring cylinder mounted on said bearing having a plurality of arcuately spaced measuring apertures, a discharge aperture plate having a discharge aperture, and radially adjustable means to vary the size of said measuring apertures, said means including screws extending into said apertures from the periphery of said cylinder.

3. The combination with a container of a dispenser unit comprising a closure cap member having a dispensing aperture, a bearing member fixed on said cap member, a rotatable measuring cylinder mounted on said bearing having a plurality of arcuately spaced adjustable measuring apertures, a discharge aperture plate having a ldischarge aperture, and spring and groove indexing means for said measuring cylinder.

4. The combination with a container of a dispensery unit comprising a closure cap member having a dispensing aperture, a bearing member fixed on said cap member, a rotatable measuring cylinder mounted on said bearing having a plurality of arcuately spaced adjustable measuring apertures, a discharge aperture plate having a discharge aperture, and indexing means for said measuring cylinder, said means including grooves on said cylinder and a yoke spring engageable therewith. l

5. The combination with a container of a dispenser unit comprising a closure cap member having a dispensing aperture, a bearing member xed to said cap member, a measuring cylinder mounted on said bearing having a plurality of measuring apertures and indexing grooves, a dis charge aperture plate having a discharge aperture, and resilient means to maintain said plate against said cylinder, said means adapted to engage said grooves for said indexing.

6. The combination with a container of a dispenser unit comprising a closure cap member having a dispensing aperture, a bearing member xed to said cap member, a measuring cylinder mounted. on said bearing having a plurality of measuring apertures and indexing grooves, a discharge aperture plate having a discharge aperture, and means to maintain said plate against said cylinder, said means including a yoke spring adapted to engage said plate, and said grooves for said indexing.
